摘　　要：本文计算分析了长方体劈裂实验的可行性，得到了抗拉强度值和试件尺寸的关系并且找到了可替代巴西试验的长方体宽高比范围，对各种宽高比所得的值进行误差分析和优劣对比，指出了替代巴西试验的长方体宽高比 .This paper analyzed feasibility of cuboid spilt test by calculation.The relation of tensile strength and cuboid's size were obtained, and the range of cuboid's ratio of width－ height was found in which cuboid spilt test can substitute base test. Tensile strength's error has been analyzed, and predominance has been compared with different ratios of width－ height, and the best ratio of width－ height has been indicated.

关 键 词：长方体 劈裂实验 巴西试验 最佳宽高比 材料 抗拉强度 拉应力值
